I can't read the number, but it looks like there is a number followed by PT (for pint) in front of the 3.1 OZ.
Converting 800 mL, I get 27.05 OZ. Under "largest whole unit" rule it should be 1 PT 11.1 OZ if I accept their rounding (meaning the true fill is Customary, not metric). If it says 1.5 PT 3.1 OZ, that is mathematically correct but a style error, they have to use successively smaller whole units until the last unit. Stupid compound numbers. >________________________________ > From: "cont...@metricpioneer.com" <cont...@metricpioneer.com> >To: U.S. Metric Association <usma@colostate.edu> >Sent: Tuesday, May 20, 2014 11:53 AM >Subject: [USMA:53841] 800 mL 3.1 oz > > > > >My wife Michele and I visited my son Itai and his girl friend Destaney the >other day to see their new place and I noticed that they have a tall >cylindrical bottle of artesian VOSS water from Norway.
